Tersus: multipart request error message when uploading file

multipart request error message when uploading fileDate: Jan 30, 2013hi,

I have developed a document management system that allows
uploading of files to a server. There's no issue of uploading of files with
small sizes. However, when a file of size of about 80MB is used for uploading,
encountered the error, Failed to process multiplepart request - file size
limit exceeded.

Did some research on this and according to
http://stackoverflow.com/questions/2947683/httprequest-maximum-allowable-size-in-tomcat
it seems that some configuration changes, seen below are required on Tomcat server.
My Tomcat version is 6.0.29.

-------------------------
In conf\server.xml

<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
                maxPostSize="67589953" />

In webapps\manager\WEB-INF\web.xml

<multipart-config>

<max-file-size>52428800</max-file-size>
<max-request-size>52428800</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>
--------------------------

Have also set max_allowed_packet=150M in Mysql my.ini

I did the above and restarted Tomcat and Mysql but problem still persist.
Had the same problem when i tried in Tersus studio.

Was wondering what can be done both on Tomcat server and Tersus Studio
to resolve the problem.

Hope you can advise.
ThanksCheers
